I'm just a little fuzzy on whether an alarm spell can alert someone inside a rope trick.
The "rope" of a rope trick is at most 30 feet long and it ends inside the rope trick. So on the one hand you must be within 30 feet. On the other hand, a rope trick is in an extradimensional space, which most would consider farther away than a mile... but some dimensions "overlap" the prime material. But then again, spells effect can't cross the rope trick's "window", but that could be seen as having the radius of the alert area not crossing the window.
I'm inclined to think you can't be alerted inside a rope trick, but RAW it just isn't clear, and RAI I have no idea ;-)
